SPECIFICATION forming part of Letters Patent No. 684,885, dated October22, 1901.

Application filed April 27, 1901.

To all whom it may concern.-

Be it known that we, WILLIAM D. THOMP- SON and SAMUEL HERBERT, citizensof the United States, residing at Detroit, in the county of Wayne andState of Michigan, have invented certain new and useful Improvements inOar-Roofs, of which the following is a specification, reference beinghad therein to the accompanying drawings.

The invention has reference generally to car-roofs, and particularly toan inner Inetallic roof formed of a plurality of metallic sheetsarranged upon the framework forming a part of the roof structure forindependent movement.

The invention consists, essentially, in the novel means employed forsecuring the sheets to the framework, in the peculiar arrangement of theplates or sheets relatively to each other, and in various other detailsof construction, as will be hereinafter set forth, and shown in thedrawings, in which- Figure l is a sectional perspective View of acar-roof embodying our invention. Fig. 2 is a similar view of a portionof the roof, showing the arrangement of the plates and the manner ofsecuring the same in position. Figs. 3 and 4 are sections taken on lines00 :n and y 3 respectively, Fig. 1; and Fig. 5 is a sectional view of amodified form of inner roof structure.

In the drawings thus briefly referred to the reference-letterAdesignates a car of any approved construction the roof of whichcomprises an internal framework composed of carlines B, purlins C, and aridge-pole D, and an external framework comprising superoarlines E,superpurlins F, and an outer or super ridge-pole Gr. Arrangedintermediate the frameworks described is our improved metallic roofing,comprising a plurality of plates arranged for independent longitudinalmovement and extending from the super ridge-pole to the eaves.

The metallic roofing referred to may be formed of a number of plates,such as H, Fig. 2, having upwardly-extending inclined flanges I at theirside edges, which engage within grooves J, formed in the under faces ofthe supercarlines. As indicated, the flanges are bent outwardly, formingobtuse angles as indicated, which extend Serial No. 57,728. (No model.)

with the plate-bodies, and the grooves within the carlines arecorrespondingly inclined, two saw-kerfs being formed in thesupercarliues,

preferably in a direction toward each other.

The plates H, as shown, are arranged intermediate the supercarlines, andon account of the inclination of the slots the plate-bodies are held incontact with the supercarlines the entire length of the latter, theinclined grooves forming practically a lock for maintaining thesheetsintheirproperposit-ion. Asshown, the plates are open-ended, which permitsof their'upper portions extending not only to the super ridge-pole butbeneath the same,

and the flanged portions of the plates at their lower ends are adaptedto bear against the usual facia K, which latter serves to prevent anyconsiderable endwise movement of the roof-sections. A groove, such as a,Fig. 3, is formed in the inner face of the facia, near its lower edge,producing a drip-passage which is arranged immediately-opposite the bodyportions of the plates to permit of the discharge of the water from theplates.

In order that a continuous metallic roof may be provided for the car,additional metallic plates, such as L, are employed and arranged beneaththe supercarlines. These plates are provided with upwardly-inclinedflanges M, which are bent inwardly to permit of their engagement withinthe saw-kerfs,as plainly indicated in Fig. 2. Thus in addition toassisting to form a continuous metallic covering the latter plates serveto clamp that portion of the supercarlines which they embrace,

thus preventing any splitting or checking of the latter which may becaused by the wrenching of the car. For the purpose of preventing thesplitting of the corners of the super carlines tie members, such as O,are used, which extend through the supercarlines, as indicated in Fig.4, and are provided at their ends with heads P, bent in angular relationto the bars to embrace the sides of the super ca'rlines, as indicated.The external roof structure is preferably provided with an outer woodencovering Q, and centrallv of the roof extends the usual running-board R.

In Fig. 5 a continuous roof structure is shown of a modified form. Inthis type only loo' one saw-kerf is formed in each supercarline whichreceives the adjacent flanges of ad j oining plate-sections. By formingthe roof in this manner less material is required and less labor isnecessary, thereby reducing the cost of construction of the roof.

From the above description of our invention it will be readily seenthatthe grooves in the form of straight and inclined saw-kerfs can bereadily and qu ickly formed within the supercarlines, which is adesirable feature of construction, and, as above stated, by incliningthe grooves as set forth they serve to prevent the plates from fallingor sagging from their position. It will also be obvious that the platesmay be readily attached or detached from between the two frameworks andindependently of each other, if desired, and that when arranged to forma continuous roof the meeting and abutting flanges of adjoining platesare inclined, so that the possibility of water leaking through the roofat the joints is prevented.

\Vhat we claim as our invention is-- 1. In a car-roof, the combinationwith an internal and an external framework composed 2. In a car-roof,the combination of the supercarlines having inclined grooves or slotsformed within and leading upwardly from their lower faces, and an innerroof formed 1 of a series of metallic plates extending uninterruptedlybeneath the supercarlines, each sheet having upwardly-inclined flangesat its side edges, and the adjacent flanges of adjoining sheets abuttingand engaging within the slots formed in the supercarlines.

3. In a car-roof, the combination with an internal and an externalframework composed 5c of carlines and purlins and supercarlines andsuperpurlins respectively, the supercarlines being provided withinclined slots or grooves leading upwardly from their lower faces, of acovering for the external framework, an inner metallic roof intermediatethe frameworks, formed of a series of metallic plates extending in acommon plane and uninterruptedly beneath the supercarlines andupwardly-inclined flanges at the side edges of the plates, the adjacentflanges of adjoining plates or sheets abutting and engaging within a theslots or grooves in the supercarlines.

4. In a car-roof, the combination of a series of supercarlines eachprovided with two grooves extending upwardly from the lower face andinclined toward each other, and a continuous inner metallic roofcomprising clamping-plates having inwardly-inclined flanges at theirside edges engaging the cor- 7c respondingly-inclined slots in thesupercarlines,and connecting-plates provided with upwardly-inclined sideflanges engaging the adjacent grooves in adjoining supercarlines.

5. In a car-roof, the combination with the supercarlines, of an innerroof formed of a series of flanged metallic plates having a slidingengagement with the supercarlines, and a facia bearing against theflanged portions of the sheets at the lower ends of the latter andprovided with a recess forming a drip-passage opposite the bodies of thesheets.

6. In a car-root, the combination with an inner framework composed ofcarlines and purlins, of supercarlines thereon, a metallic roof formedof a series of plate-sections abutting at their side edges and extendinguninterruptedly beneath and covering the under faces of thesupercarlines, and side flanges upon the plate-sections engaging saidsupero
